Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and in particular to an integrated tobacco topping and bud-suppressing operation device. Background Technology

[0002] Topping and bud suppression are important measures in tobacco field production for regulating plant nutrition and leaf quality. Topping removes apical dominance, allowing more nutrients to be distributed to the leaves, promoting the full development and maturation of the middle and upper leaves, and enhancing nicotine synthesis, thus increasing tobacco yield and quality. Combined with bud suppression, topping removes terminal and axillary buds, depriving aphids and other pests of their tender organs for egg and larval survival, reducing aphid damage and viral diseases transmitted by aphids. Currently, the basic process for manual topping and bud suppression in tobacco involves farmers manually breaking off inflorescences or cutting them with scissors, collecting the inflorescences and taking them out of the field. Then, diluted chemical bud suppressant solution (in cups or bottles) is poured downwards from the stem cut, ensuring the agent covers most of the stem surface, especially the leaf axils where the stem connects to the leaves.

[0003] Existing tobacco topping and bud suppression machinery typically employs a separate operation mode: topping followed by bud suppression. The topping and bud suppression device moves continuously between rows with the field vehicle, using vertically or inclined rotating cutters to cut the inflorescences at the top of the tobacco plant. Then, a bud-suppressing agent is sprayed above the cut. On the one hand, the constantly rotating cutters often damage and break the cut inflorescences, making them difficult to collect intact, or they are simply scattered in the field without any collection process. On the other hand, the moving topping and bud-suppressing device can only spray the bud-suppressing agent onto the cut surface of the tobacco plant within a short period after the plant passes the spraying device. The limited amount of bud-suppressing agent cannot cover a large area of ​​the tobacco stem surface to achieve a good bud-suppressing effect, and there is also a problem of wasting bud-suppressing agent. Therefore, it is necessary to adopt a more refined topping and bud-suppressing operation mode for tobacco field production, achieving both the cutting and complete collection of the cut inflorescences, and the application of a sufficient amount of bud-suppressing agent to the stem surface at the cut surface of the tobacco plant. Summary of the Invention

[0036] Please see Figures 1-5 This invention discloses an integrated tobacco topping and bud suppression execution device, comprising:

[0037] Connecting cylinder 1, the upper end of connecting cylinder 1 is connected to negative pressure equipment through inflorescence conveying pipe;

[0038] The clamping mechanism includes a clamping cylinder, a drive unit 2, and a connecting rod transmission unit 3. The inner cavity of the clamping cylinder is connected to the inner cavity of the connecting cylinder 1. The clamping cylinder is formed by multiple arc-shaped clamping cover plates 4. Multiple drive units 2 are installed on the outer wall of the connecting cylinder 1 in a one-to-one correspondence with the arc-shaped clamping cover plates 4. Multiple connecting rod transmission units 3 are installed on the outer wall of the connecting cylinder 1 in a one-to-one correspondence with the drive units 2, with one end of each connecting rod transmission unit 3 being connected to the output end of the drive unit 2 and the other end being hinged to the outer wall of the arc-shaped clamping cover plate 4.

[0039] The cutting mechanism includes multiple fan-shaped blades 5, which are fixed to the lower inner wall of the arc-shaped clamping cover plate 4 in a one-to-one correspondence. The blades are fan-shaped and arranged perpendicular to the inner plate surface of the arc-shaped clamping cover plate 4. The arc-shaped side of the fan-shaped blade is fixed to the lower inner wall of the arc-shaped clamping cover plate 4, and the straight side on both sides is provided with a cutting edge.

[0040] The application mechanism has multiple bud inhibitor outlets 41 below the corresponding blade 5, and the application mechanism is fixed on the inner wall of the arc-shaped clamping cover 4 at the corresponding bud inhibitor outlet 41.

[0041] When the clamping mechanism is in the clamping state, multiple arc-shaped clamping covers 4 come together to form a closed clamping cylinder, multiple blades 5 are in the same plane and the cutting edges of adjacent blades 5 are closely fitted to form a closed circular cutting surface, and multiple drug application mechanisms are closely fitted to form a closed circular clamping surface; when the clamping mechanism is in the non-clamping state, multiple arc-shaped clamping covers 4 unfold to all sides, and multiple blades 5 and multiple drug application mechanisms unfold accordingly.

[0042] The clamping mechanism gathers the inflorescence through a retraction operation, while the cutting mechanism inside the clamping mechanism cuts off the inflorescence. The application mechanism then applies a bud-inhibiting agent to the cut. Simultaneously, a negative pressure device uses the inflorescence transport pipe to deliver negative pressure airflow into the inner cavity of the connecting cylinder, transporting the inflorescence along the inner cavity of the connecting cylinder 1 and the inflorescence transport pipe to a designated location for collection. After collection, the clamping mechanism unfolds to await the next work cycle.

[0043] The inflorescence conveying pipe is made of flexible material and has a smooth inner wall.

[0044] The drive unit 2 includes a support 21 and a servo motor 22. The support 21 is fixed to the outer wall of the connecting cylinder 1, and the servo motor 22 is mounted on the support 21 by bolts.

[0045] In one specific embodiment, each linkage transmission unit 3 includes a driving link 31 and a driven link 32. One end of the driving link 31 is connected to the output end of the drive unit 2, and the driven link 32 is hinged to the other end of the driving link 31. The other end of the driven link 32 is hinged to the outer wall of the arc-shaped clamping cover plate 4. The drive unit 2 drives the driving link 31 to rotate, which in turn drives the driven link 32 to rotate, allowing the arc-shaped clamping cover plate 4 to rotate away from or towards its center to unfold or retract.

[0046] In one specific embodiment, multiple guide rods 33 are also provided. An elongated groove 42, extending along the axial direction and passing through one end near the connecting cylinder 1, is formed on the inner wall of the arc-shaped clamping cover 4. Each guide rod 33 corresponds to a driving connecting rod, with one end hinged to the middle of the driving connecting rod 31, and the other end sliding within the groove 42 along its length. Multiple sliders 331 are fixed at intervals on the two opposite side walls of the groove 42 along its length. Slide rails 332, which slidably engage with the sliders 331, are provided on both sides of the guide rods 33, allowing the guide rods 33 to slide within the groove 42 along its length. The cooperation between the slide rails 332 and the sliders 331 provides a guiding function, preventing the arc-shaped clamping cover 4 from rotating unrestricted during rotation and thus failing to close.

[0047] In one specific embodiment, a plurality of limiting rods 34 are also provided. Each limiting rod 34 corresponds one-to-one with a guide rod 33, and one end of each limiting rod 34 is hinged to the outer wall of the connecting cylinder 1 below the corresponding driving part 2, and the other end is hinged to the other end of the guide rod 33 located in the slide groove 42. The limiting rods 34 further limit and guide the arc-shaped clamping cover plate 4 to prevent the arc-shaped clamping cover plate 4 from unfolding at too large an angle, making it inconvenient to retract.

[0048] In one specific embodiment, it also includes a sealing cylinder corresponding to the upper end of the clamping cylinder. The inner cavity of the sealing cylinder is interconnected with the inner cavities of the clamping cylinder and the connecting cylinder 1. The sealing cylinder includes a plurality of circumferentially arranged arc-shaped sealing cover plates 6. The arc-shaped sealing cover plates 6 correspond one-to-one with a plurality of limiting rods 34, and the arc-shaped sealing cover plates 6 are fixed to the middle of the limiting rods 34 on the side close to the inner cavity of the clamping cylinder.

[0049] When the clamping mechanism is in the clamping state, the arc-shaped sealing cover plate 6 is driven by the limiting rod 34 to close together to form a sealing cylinder. The top of the sealing cylinder can abut against the bottom of the connecting cylinder 1, and the bottom can abut against the top of the arc-shaped clamping cover plate 4. When the clamping mechanism is in the non-clamping state, the arc-shaped sealing cover plate 6 is driven by the limiting rod 34 to expand in all directions.

[0050] The connecting cylinder 1, the sealing cylinder, and the clamping cylinder are all tightly fitted together, and their internal cavities are connected to the inflorescence conveying pipe. The cut inflorescences can be conveyed along the inner cavities of the connecting cylinder 1, the sealing cylinder, and the clamping cylinder, as well as the inflorescence conveying pipe, for collection by a negative pressure device.

[0051] In one specific embodiment, an anti-collision pad 7 is also provided on the outer wall of the connecting cylinder 1 above the active connecting rod 31. The anti-collision pad 7 is a rubber pad to prevent the active connecting rod 31 from colliding with the connecting cylinder 1.

[0052] In one specific embodiment, the lower part of the arc-shaped sealing cover plate 6 is provided with multiple ventilation holes 43 corresponding to the upper part of the blade 5, which are used to balance the air pressure inside the clamping cylinder and the outside air pressure, so that the arc-shaped clamping cover plate 4 can be unfolded again after the inflorescence is transported.

[0053] In one specific embodiment, the system further includes a sprout inhibitor supply mechanism 8, which comprises a sprout inhibitor storage tank, a delivery pump, and an infusion pipe 81. The inlet of the delivery pump is connected to the sprout inhibitor storage tank. An infusion channel 82 is provided inside the arc-shaped clamping cover 4 corresponding to the area below the blade 5. Multiple sprout inhibitor outlets 41 communicating with the infusion channels 82 are provided on the inner side wall of the arc-shaped clamping cover 4, and a sprout inhibitor inlet communicating with the infusion channels 82 is provided on the outer side wall of the arc-shaped clamping cover 4. One end of the infusion pipe 81 is connected to the outlet of the delivery pump, and the other end is connected to the sprout inhibitor inlet. The sprout inhibitor is delivered into the infusion channels 82 through the sprout inhibitor supply mechanism 8 and flows out from the sprout inhibitor outlets 41 into the application mechanism to apply the agent to the cut and the stem below the cut.

[0054] The negative pressure equipment, servo motor, and delivery pump are all electrically connected to an external control system, which controls their opening and closing.

[0055] In one specific embodiment, the infusion tube 81 includes an annular main liquid tube 811 and multiple dispensing hoses 812. The annular main liquid tube 811 is sleeved on the outer wall of the connecting cylinder 1. The inlet end of the annular main liquid tube 811 is connected to the outlet of the delivery pump. The annular main liquid tube 811 has multiple outlets evenly distributed circumferentially. The inlet ends of the multiple dispensing hoses 812 are connected to and communicate with the outlets of the annular main liquid tube 811, and the outlet ends are connected to the inlet of the sprout inhibitor.

[0056] In one specific embodiment, a buckle 9 is also provided. The dispensing hose 812 is sequentially fixed to the outer wall of the connecting cylinder 1, the active connecting rod 31, the driven connecting rod 32, and the arc-shaped clamping cover plate 4 by multiple buckles 9. This allows the dispensing hose 812 to move synchronously with the actuator, preventing pipeline damage and leakage, which would affect tobacco growth.

[0057] In one specific embodiment, the application mechanism includes a plurality of fan-shaped sponge blocks 10, and the arc-shaped surface of each sponge block 10 is connected one-to-one to the inner wall of the arc-shaped clamping cover plate 4 at the sprout inhibitor outlet 41.

[0058] When the application mechanism is working, multiple sponge blocks 10 are brought together by the arc-shaped clamping cover 4, with adjacent sponge blocks 10 tightly clamping the stem. The bud-inhibiting agent flowing from the outlet 41 soaks into the sponge blocks 10. The bud-inhibiting agent can flow downwards from the cut to ensure precise application to the stem surface, avoiding waste caused by applying the bud-inhibiting agent to areas outside the tobacco stem and preventing the bud-inhibiting agent from being applied to other tobacco buds and stems, thus avoiding affecting their growth. After the application mechanism finishes working, the multiple sponge blocks 10 are unfolded by the arc-shaped clamping cover 4.

[0059] The present invention provides an integrated tobacco topping and bud suppression operation device that can be mounted on tobacco field operation vehicles.

[0060] The basic working steps of the integrated tobacco topping and bud suppression execution device of the present invention include:

[0061] 1. The tobacco field operation vehicle, equipped with the actuator, reaches the inflorescence of the tobacco plant that needs to be topped. The servo motor 22 drives the active linkage 31 to move forward, and through the driven linkage 32, guide rod 33, and limit rod 34, ultimately drives the arc-shaped clamping cover 4 from the unfolded state to the closed state. During this transition, the inflorescence is enclosed in the clamping cavity formed by the arc-shaped clamping cover 4. The stem below the inflorescence is cut by a closed cutting surface composed of multiple fan-shaped blades 5, while the stem below the blades 5 is clamped and fixed by multiple fan-shaped sponge blocks 10.

[0062] 2. The negative pressure equipment inputs negative pressure airflow into the actuator through the inflorescence conveying pipe. The wrapped and cut inflorescences are collected by moving along the inflorescence conveying pipe under the action of negative pressure airflow. At the same time, the conveying pump is started to input the bud inhibitor dilution into the infusion channel 82, so that it flows through the bud inhibitor outlet 41 to the sponge block 10. The bud inhibitor dilution finally reaches the tobacco stem from the sponge block 10 and flows down the surface of the stem from the cut.

[0063] 3. Once the inflorescences are collected and sufficient bud-inhibiting agent dilution has been applied to the surface of the tobacco plant stems, the negative pressure equipment is turned off to stop the negative pressure airflow into the inflorescence delivery pipe, the delivery pump is turned off to stop the input of bud-inhibiting agent dilution into the delivery channel 82, and the servo motor drives the arc-shaped clamping cover 4 to move in the opposite direction, returning it from the closed state to the open state.

[0064] 4. The actuator moves with the field work vehicle to the top of the next tobacco plant, preparing for the next work cycle.
